<p>A lock cylinder for use with either a deadbolt lock or a key-in-the-knob lock. The lock cylinder includes a hollow cylindrical body having a radially projecting, pin-containing chamber, extending along the length of the body, and a cylinder plug rotatably accommodated within the body. The plug holds a series of pins, which can be brought into alignment with the pins in the chamber, and the plug has a slot for accepting a key. Two tailpieces are provided, either of which may be alternatively secured to the cylinder plug in non-rotatable relationship to the plug. One of the tailpieces is cooperable with the mechanism for operating a deadbolt lock, and the other tailpiece is cooperable with the mechanism for operating a key-in-the-knob lock. One end of the cylinder plug is formed with a transverse slot and an annular slot, an extension at one end of each tailpiece fitting into the transverse slot, and a resilient snap ring fitting into the annular slot to prevent separation of the tailpiece from the plug.</p> |
